+* A Raspberry Pi 3, 4, or 5 and SD card for the operating system. For the 4 or 5, any amount of RAM should work just fine. Note that only the 5 has two full serial interfaces and thus is the only model that can connect to the motor controllers (Roboclaws) and run bluetooth at the same time.
 
 > (*) The reason you need 14V is that the 12V regulator needs a [dropout voltage](https://www.pololu.com/product/2855#dropout) on top of the output voltage in order to provide 12V. A 12V battery will not work adequately.
